Verdict
The clearest difference is in-app purchases: S2M Companion at none against 4D Motion's 6. S2M Companion also leads on update cadence (every 11 days vs monthly). 4D Motion's advantage is device support (4 vs 1) and iOS requirement (14.0 vs 18.0). On price and ads there is nothing between them.
